Chinese Bowl Tang Dynasty Sancai Glazed Pottery Cup

A set of two Chinese Tang dynasty Sancai glazed bowls.
The sancai technique dates back to the Tang Dynasty. How ever, the colors of the glazes used to decorate the wares of the Tang Dynasty generally were not limited to three in number. In the West, Tang sancai wares were sometimes referred to as egg-and-spinach by dealers, for their use of green, yellow, and white (though the latter of the two colors might be more properly described as amber and off-white or cream).
These items probably has been excavated in the Luoyang area.
One bowl is still in good condition. The other one is damage by age.
Size, 16 cm wide and 6 cm tall.
